backup error

While doing a daily backup, I have started to get an windows popup error message that says a delayed write occured and data was lost. The Norton backup log says an error occurred but I cannot see what file is causing the error. How can I figure out what file is causing the problem?

The computer system log shows 2 issues. This was actuallty about 48 hours after I manually started a brand new backup. When I look at the backup via "Norton Backup Drive" it looks like OK but there are thousands of files.

Thanks in advance for any help or suggestions.

Re: backup error

I do not know what is happening and if anyone else thinks they have any idea they should feel free to jump in.

In the meantime.... You say that this is a new backup set. Is it to a new drive? Is the drive a new one or one that you have used much before?

Have you successfully run N360 backups successfully to other sets previously, whether to the problem drive or elsewhere?

Can I suggest that you use the restore feature to look at the files in the new backup to try and get some idea whether most of the backup has succeeded or most has failed. If most has succeeded then I would suggest you try running it again and seeing if you get a similar error, at least this time there should be far fewer files to trawl through (all being well).

Re: backup error

Sorry I didn't get back sooner but for some reason I did not get an email notification that anyone responded.

This over a network and it is wired! The pc computer I am using as a file server is running XPpro and the drive that is mapped is an external one via USB. Still 48 hours seemed like a very long time for about 50GB.

This is a new backup set but on a drive which I did use before. I did not delete the old set first so maybe that was part of the issue with it taking so long. Now it seems to be running daily and I have not seen the error again so I am stumped and no easy way to tell what file caused the problem. The backup set seems to be the right size so I am guessing that at least most of the files are backup up.

Just to be sure, I created a simple copy backup to a USB drive connected directly to this pc. It took about 2 hours total and I then disconnected this drive. So I know I have a good backup that is not connected to anything. But I nne the daily backup to run automatically because this is my wife's computer and she just won't do it.

Re: backup error

I am not sure what is going on but the error has not reappeared. Either it was a temporary network issue or the file is no longer being backup up or the file was bad and somehow got fixed. I changed nothing. It seems weird and I still have no way to tell what file to check. Even if the problem was network related, I would like to check to see if that file is in the backup set. Since I changed nothing, doesn't that point to something with the file changing and not the networkk?

Re: backup error

Glad the issue seems to have gone away. Under the circumstances (a temporary error) we may never know what happened but to me it looks like a temporary network error. However I suspect that DaveH has a greater knowledge of these things than I do, so he may well have a different view.
